Pretty new to keeping tropical fish and trying my best to keep them well looked after.
After the last few water changes I must have removed more water than I have replaced so the water line is lower than I want it to be.
I changed the filter and around 10% of the water yesterday. Replaced it with conditioned water.
Now want to add more to bring the water line back up. What's the best way to do this and how long should I wait?
Thanks!
